We hope to apply this method to our clinical work, but the following questions seem to bother us: 1) Specifically, how is intracranial hypotension diagnosed? Is it by judging whether pachymeningeal enhancement or subdural collections or venous engorgement or brain stem slumping in the MR images or a combination of ≥2 of the above? 2) How does the brain stem slumping manifest by imaging only distinguish it from Arnold Chiari malformation? 3) How does one eliminate the influence of head displacement on the interpeduncular angle caused by the displacement of the head during plain MR imaging? If the above problems are solved, the clinical applicability of the interpeduncular angle will be greatly enhanced. We are very grateful to Wang et al for the study, which gave us a new way to evaluate intracranial hypotension on brain MR imaging.</p><div class="section ref-list" id="ref-list-1"><h2 class="">Reference</h2><ol class="cit-list ref-use-labels"><li><span class="ref-label">1.</span><a class="rev-xref-ref" href="#xref-ref-1-1" title="View reference 1. in text" id="ref-1">↵</a><div class="cit ref-cit ref-journal" id="cit-41.1.E1.1" data-doi="10.3174/ajnr.A6120"><div class="cit-metadata"><ol class="cit-auth-list"><li><span class="cit-auth"><span class="cit-name-surname">Wang</span>  <span class="cit-name-given-names">DJ</span></span>, </li><li><span class="cit-auth"><span class="cit-name-surname">Pandey</span>  <span class="cit-name-given-names">SK</span></span>, </li><li><span class="cit-auth"><span class="cit-name-surname">Lee</span>  <span class="cit-name-given-names">DH</span></span>, <span class="cit-etal">et al</span></li></ol><cite>. <span class="cit-article-title">The interpeduncular angle: a practical and objective marker for the detection and diagnosis of intracranial hypotension on brain MRI.</span> <abbr class="cit-jnl-abbrev">AJNR Am J Neuroradiol</abbr> <span class="cit-pub-date">2019</span>;<span class="cit-vol">40</span>:<span class="cit-fpage">1299</span>–<span class="cit-lpage">1303</span><span class="cit-pub-id-sep cit-pub-id-doi-sep"> </span><span class="cit-pub-id cit-pub-id-doi"><span class="cit-pub-id-scheme-doi">doi:</span>10.3174/ajnr.A6120</span><span class="cit-pub-id-sep cit-pub-id-pmid-sep"> </span><span class="cit-pub-id cit-pub-id-pmid"><span class="cit-pub-id-scheme-pmid">pmid:</span>31296521</span></cite></div><div class="cit-extra"><a href="/lookup/ijlink/YTozOntzOjQ6InBhdGgiO3M6MTQ6Ii9sb29rdXAvaWpsaW5rIjtzOjU6InF1ZXJ5IjthOjQ6e3M6ODoibGlua1R5cGUiO3M6NDoiQUJTVCI7czoxMToiam91cm5hbENvZGUiO3M6NDoiYWpuciI7czo1OiJyZXNpZCI7czo5OiI0MC84LzEyOTkiO3M6NDoiYXRvbSI7czoxODoiL2FqbnIvNDEvMS9FMS5hdG9tIjt9czo4OiJmcmFnbWVudCI7czowOiIiO30=" class="cit-ref-sprinkles cit-ref-sprinkles-ijlink"><span><span class="cit-reflinks-abstract">Abstract</span><span class="cit-sep cit-reflinks-variant-name-sep">/</span><span class="cit-reflinks-full-text"><span class="free-full-text">FREE </span>Full Text</span></span></a></div></div></li></ol></div><ul class="copyright-statement"><li class="fn" id="copyright-statement-1">© 2020 by American Journal of Neuroradiology</li></ul><span class="highwire-journal-article-marker-end"></span></div><span class="related-urls"></span></div></div>  </div>
